J cathayensis, a native Chinese walnut, is a flower bearing tree where the nuts cluster into large groups called grapes. The wood from the tree is used in furniture making. The Chinese walnut can survive in many different types of soils varying in pH and moistness

Stephens et al. produced ‘draft’ genomes for six Juglans species and the related Pterocarya stenoptera. The draft genome contigs were aligned to the Juglans regia genome scaffolds using nucmer (see paper for details). These alignments are available as tracks on the J. regia JBrowse.
